Blizzard screwed us with a small update they did - and they're the only ones that can fix it fully, we can only mask it. Make sure all your addons are up to date, possibly even checking alpha versions to see if they include any updates that mention it.

In short a check regarding the state of parental controls is being fired way more often than it should be, every time the micromenu updates.
That is already updating for frames it is no longer responsible for, in addition to the ones it is.

If the functionality is not affected then you simply hide the message with idbpc taint fix @ Curse.
That basically hides the error popups associated with that specific error, so that you don't see them.
Something like buggrabber will still catch the error, so I would advise disabling its sound effect should you use that.

Grab the latest alpha version. Our release schedule isn't the greatest but the alpha was ready to go shortly after 5.4.1 landed, and tweaked a few times. Hopefully a new release version will be out in the next couple of days.
